SPECIFICATION forming part of Letters Patent No. 337,327. dated March 2. 1886.

Application filed December 24. 1885. Serial No. 186,632. (No model.)

To @ZZ whom it may concern:

Be it known that LWILLIAM H. HERBERT- SON, of Brownsville, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvementsin Car-Axle Lubricators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention has relation to lubricating devices for ear axles; and it consists in the improved construction,arrangement, and combination of parts, which I shall proceed to fully describe, and the particular points of novelty in which I shall specifically point out in the claims hereto appended.

In the accompanying drawings, Figure 1 is a view in elevation, partly in section, of a car wheel and axle embodying my improvements. Fig. 2 is a sectional view throughthe hub, the axle being shown in position in elevation. Fig. 8 is a section through one side of the hub, showing its interior construction; and Fig. 4 is a detail view showing the cap for the oil-chamber.

Like letters of reference mark the same parts in all the gures of the drawings in which they may occur.

Referring to the drawings by letters, A is the spindle of the axle,which is provided with the usual collar, a, and any suitable means for preventing the accidental removal of the wheel therefrom. A

B is the wheel, having a hollow hub, C.

D D D are three bars, which are fitted and held between the inner surfaces, c c', ofthe front and rear sides of the hub. rIhe inner sides of these bars are curved to fit closely to the spindle, and their longitudinal axes are inclined to the longitudinal axis of said spindle. They are fitted rigidly in position in the hub, so that they will always turn therewith.

E is a channel drilled through the front of the hub to give communication with the interior thereof.

F is a rod or pivot rigidly secured in the hub, and projecting slightly beyond the front thereof, and has pivoted upon it a cap, H, Y

which serves to cover the opening of the channel E. This cap is provided with projections h, by which it may be readily turned, and a perforation which may be made, when desired, to coincide with the channel E.

Oil being introduced into the central cavity of the hub through the channel E will fall on the bars M, and be carried around, so as to thoroughly lubricate every portion of the spindle. When the wheel revolves in one direction, the oil will be carried by these bars, owing to their inclination, toward the outer end of the spindle, and if in the other direction toward the inner end. volves, the oil is continuously thrown about in the hub-chamber, and as the channel through which the oil is introduced is tightly closed by means of its cap there is no waste of oil, and consequently a great saving is effected.-

Ihe hub has an inner extension, C', which covers the collar c of the spindle and prevents any drainage or dirt from the car collecting at this point and absorbing the oil.

The cap is held rigidly in position by riveting the end of its pivot, said pivot being cast into the hub at its inner end.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

l. In combination, the hub having the central cavity or oilchamber and a channel leading therefrom, a bar cast therein and projecting beyond the front thereof, and a circular cap pivoted on said bar, and provided with a perforation which may be made to register with the channel,when desired, said cap being securely held by riveting the outer end of its pivot-bar, and having projections by which it may beturned, as set forth.

2. In combination, the hollow hub, the in- Y clined bars secured therein, and having their inner sides curved to fit the spindle, the oilchannel through the hub, and a suitable cap pivoted on the hub, substantially as set forth.

In testimony that I claim the foregoing as my own I hereto affix my signature in presence of two witnesses.

WILLIAH H. HERBERTSON.
